The same part is designated by the same reference numeral wherever it occurs 8 throughout the several views. I

In carrying outmyinvention, I. propose to employ a flow of water or' other cooling and condensing fluid to exert an aspirating 0r injector action upon the heated vapors, gases or the like to be treated, within .a closed chamber to which such vapors, gases or the i like are delivered, to thereby draw such vapors .or. gases into and carry the same along with the flow of condensing material, thereby. cooling and condensing such vapors or gases and enabling the condensed product to e separated and recovered, and at the same timecreating a vacuum condition of high degree to facilitate the operation and render the same more effective and economical. I have found that .where hydrocarbon vapors are treated, as for instance in the production of lubricants and lubricating oils by distilling crude oil, wateris a suitable condensing agent to employ, and in accordance with my, in-

vention I proposeto eflect a directseparatlon of the condensates or elements obtained from the heated hydrocarbon vapors from the such vapors, utilizing the difference in specific gravities of the condensates in effectby reducing the load on the pump or Other means emplo ed to draw the vapors or. gases from the distillationor other source and cause tions.

'In general, in carrying out my invention the heated vapors or gases are delivered or 1 drawn into a closed chamberiand therein-sub-y jected to the aspirating or injector actionof a 4 cooling medium which is caused to flow through such chamber, thecooled vapors or gases passing along with thecooling medium into what I shall call a separating chamber, the vapors or gases and cooling me ium being I given aiwhirl within the separating chain her to create eddies which aid in the natural tendenc of the condensates to separate from the cooling medium by reason of their difii'en,

, ences in specific gravities. I also propose to conduct ofi the separated condensates and cooling medium while maintaining a sub- .stantially constant but controllable e uncondensed gases or vapors, in accordance with my invention, are successively subjected to the condensing. or cooling action of suitable niedia to separate out or absorb therefrom the condensable constituents 'of such gases or vapors, thereby successively reducing the volume of the gases or vaporsv under'treat- 'ment and hence, also, maintaining or even increasing the v'acuum'condition under which the o erations are carried on. In-this manner efiiciency of the condensing-operation, reduce to the time required to effect the distillation,

reduce the fuel requiredto eflect the distillation, avoid the possibility of the gases or vapors remaining too 1611 in the still .which would destroy some'of t e valuable constituents of the gases or vapors, increase the capacityof the output or quantity ofco'n'densates recovered as well as enhancethe qualitythereof, control the viscosity andspecific-gravity of the, recovered products or condensates, and" secure and attain many other advantages, and deliver eventually a betterquality of gas or vapor after'thecondensing, scrubbing and absorbing operations have extracted therefrom the recoverable constituents.-

66 It will be apparent thatthe process ofmy water employed to effect the condensation of the same to pass through thevarious 'operavel and supply within the separating chamber. The

am' enabled to secure an increased invention might well be carried out in a wide variety of forms of apparatus.

While I have shown and will describe my invention as applicable to the treatment of hydrocarbon vapors'delivered from a crude oil distilling apparatus, in the production of refined, lubricating and other oils, Ito which purpose my invention is particularly well adapted, nevertheless my invention isnot to be limited or restricted in this respect-as it is also suitablefor use in treating other vapors or gases. i f v 'In the ,'drawings 1 have shown the, closed chambers 1 each of which designed to be connectedthrough a pipe or other connection ,2 with a still,retort'or other source of production of the vapors or gases to be treated.

I will refer to, the chambersl as the first vacuum chamber, andwhile I have shown twosuch chambers my invention is not to be limited or restricted in this respect. In accordance with my invention, I .pro

pose to maintain a vacuum in the chambers and this may be accomplished in various ways. F or example,- by subjecting the gases or vapors in sai'dchambers to the condensing effect of a cooling medium so app'lied as to not only eflect a condensing action upon the hot gases or vapors but also an aspirating action tending to draw thegases or vapors into the chamber .from the 'distilling ap'pw ratus, and to causethe condensed portion as well as the uncondensed gases andvapors to be" drawn from the chamber and carried. along with he cooling medium and delivered, into a -separating chamber indicatedfat 9, .where separation takes place between thecondensate productsof the vacuum chamber 1, the remaihingjunconderised gases or. vapors, and the cooling medium employed,

as will be more fully described hereinafter.

In practice,I prefer to supplythe cooling medium-under a hydrostatic head which will augment its action in drawing in and carry 1 have shown simple, and efficient aspirat- -.ing along with it the gases or vapors to be condensed.

ing or injecting apparatus for this purpose which, in the illustrative arrangement shown.

the chamber consists of a pipe 5, which extendsthroughf 1, eing connected at its upper end to a suitable source of supply of cooling medium, say, for example, water. -As shown, the upper end of the pi'pe 5 is connected-to a tank or reservoir e0, into which wateris sup,

pipe section 50 intermediate the heads 51, 52,

is provided with a series of openings 53. The

head 51 at the upperend of the pipe section 50 is formed with a central funnel shaped passage 54, the pipe section 50 at its upper endor openings 55 to the central bores thereof.

The upper tapered end of head 51 is seated against and centered by a series of lugs 56,

mounted upon the under surface of the top or cover of the chamber 1. The upper section of pipe 5 passes through an opening in this top or cover and registers with the funnel bore 54; of the head. In like manner, the

- lower tapered end of head 52 is seated upon and centered by lugs 57, on the upper surface of the bottom ofchamber 1. Intermediate the heads 51, 52 and strung upon the pip g; section 50 are a series of funnel shaped menrbers 4, as shown in Figs. 5, 6 and 7. Each member 4 is formed with an upper funnel shaped portion within which are arranged lugs 58, which form a centering seat for the lower tapered portion of the member 4 next -above.it when assembled in nested relation thereto, said lugs also serving to offset the nesting surfaces of the members from each other. Each member 4 is also provided with an annular flange 59, through which are formed slots 60, which open intothe funnel bore of the next adjacent member 4 into which it is nested. The bores of the members 4 register with the openings 53 in the pipe section'50.

In the manner above described, the vacuum'producing means are assembled within the chambers 1, the pipe section 50, constituting the body ofsuch means, forming a pas-.

sage through which the cooling medium fiows under'the influence of gravity and of the hyhence exerts a strongly-pulling force upon the gases or vapors to draw the same from the distilling apparatus. Thus are realized rapidity of operation, a reduced amount of fuel for-operating the distilling apparatus, and avoidance of losses in leaving the gases or vapors for too long a time in the distilling apparatus. The provision of the openings 55, in head 51, permits the hottest and most highl expanded. gases or vapors entering the c amber 1, and which naturally would tend to collect in the upper portion of said chamber, to be quickly drawn into the vacuum body and into the stream of cooling medium at the coolest part of the latter. This very greatly increases the efficiency of the apparatus. Whatever precipitation of condensates takes place within the chamber 1 collects in the bottom of said chamber, and the openings 55 in head 52 permit such condensates to be instantly drawn into the stream of cooling medium flowing through said head, thus again adding to the efficiency of the apparatus and aiding in maintaining the high vacuum within chamber 1. In practice, I prefer to form the bore of'the head 52 with anenlarged chamber 61, see Fig. 4.- This permits the stream of cooling medium to break by expansion into this'chamber, thereby bringing the gases, vapors and condensates n medium.

It is preferable to create eddies or whirls in the mass of cooling medium and condensates delivered from the vacuum chambers 1 into the separating chamber 9. This can be accomplished in various ways. A simple arrangement is shown wherein the rim of the upper open ends of the cups 10, are provided with tangentially arranged slots 46. In operation the cooling medium,. condensates, gases, and vapors aredelivered by the pipe 5 into the open cup 10, which fills up, the uncondensed gases or vapors bubbling up through the contents of the cup, thereby aiding materially in effecting the desired condensing and precipitating action, said gases and vapors eventually tending to colleet'in to more intimate contact with the coolingthe upper portion of chamber 9, and being further treated as will presently be more fully explained. At the same time the cool-' ing medium along with the condensates spill over the rim at the upper open end of cup 10, a portion thereof spilling through the tangential slots 46, thereby creating the whirls or eddies in. the body of the substances which collect in the chamber 9. Not only does the cup arrangement impart eddies or whirls-to the cooling medium and condensates, but it also forms a water seal or look to prevent any back flow-into pipe 5 of gases or vapors from chamber 9. By reason of the eddies or whirls produced in the liquid delivered into chamber 9, the condensates of lighter specificv gravity are enabled to rise and float on the top of the cooling medium and are propelled towards the'centerof chamber 9, and are thus prevented from formin with the cooling medium or rom being rean emulsion tained within the body of the mass of cooling which the cooling medium, with the condensates floating on the surface thereof, is directed to the center of the chamber 9. Interposed in these guiding channels are suitable resistances 47, the function of which is to break up the eddies or whirlsin the mass of liquid and facilitate the separation of the condensates from the cooling medium. In the illustrative arrangement shown, these resistances are in the form of fluted or corrugated sheets disposed in parallel relation to each other within and in the direction of length of the restricted passages 62, the travel of the liquids through said passages towards the center of the chamber 9 being past and between said sheets or plates.

The condensates floating on the top of the mass of cooling material, and as well, the cooling medium itself, which areconstantly being delivered into chamber 9, may be drawn off from said chamber in any suitable or con venient way. In the case of the cooling medium I have shown an exhaust pipe 25 extending into chamber 9, and having its inner end bent down into a depression 26 formed in the bottom of said chamber. The hydrostatic head-of the liquid contained in said chamber 9, forces the cooling medium to flow out through the exhaust pipe 25. If desired, said pipe may have a bend therein, asindicated at 63,- to form a trap to prevent reverse flow.

In the case of the condensates,I provide an exhaust or drawing-0d pipe connection 24, having also areverse ,bend 64 to form a trap, and'I provide means at the inner end of the draw-ofi' pipe to control the height of the level'of the mass of liquid within chamber 9. In the illustrative arrangement shown, the inner end of the draw-off pipe 24 is upturned and an open ended sleeve 11 telescopes'thereover. This sleeve is carried by a rack bar 27, see Figs. 1 and 13, which is engaged by a pinion 65 on a shaft 66, whichextends through the wall of chamber 9 and carries a hand wheel 28 by means of which said shaft may-be rotatively adjusted so as to raise or lower. the sleeve 11, thereby adjusting the height to. which the level of the contents of chamber 9 must rise before draW-ofi' occurs through pipe 24. f

-As above'described, the uncondensed gases or vapors delivered into chamber 9 tend to collect in the upper part of the chamber. In

order to remove from such gases or vapors any other condensable content thereof, I prefer to subject the same again to'the action of a cooling medium. To-thisend a condenser chamber 12 opens freely into the upper part of chamber 9, preferably through the top thereof, and the gases or vapors instead of collecting and remaining in chamber 9, as-

. cend into and pass through the chamber 12.

A cooling medium, such for example Wa'ter, is admitted mto the upper end of the chamber 12, as, for instance, through a spraying device 14, so that the ascending gases or pose, and in order to support and retain the scrubbing material in chamber 12, I provide said chamber with a perforated bottom as indicated at 13 in Fig. 1.'

It is undesirable to permit the cooling medium which is employed in chamber 12, and the condensates carried down with such medium, to be precipitated directly into the separating chamber 9 as that Would create agitap tion of the contents of chamber 9 and prevent the proper eflicient and expeditious separation of the condensates from the cooling medium. .To prevent this I mount an umbrellashaped shield or baflie plate '16 in the upper part of chamber 9, the diameter or dimension of the rim or boundaryedge of said shield being smaller than the internal dimension of the chamber 9 as is shown in' Fig. 1. This alfords an opportunity for the cooling medium and condensates from chamber 12 to bedeflected downwardly along the upper surface of the shield and to spill over the rim or boundary edge of saidshield' and to trickle or flow down the inner surface of the side walls of chamber 9 thereby avoiding any agitation of the contents of the said chamber 9.

It Will also be observed that the gases or vapors in chamber 9 must also pass around the outer rim or edge of shield '16 in reaching the chamber 12 from chamber 9. This is advantageous for the reason that the cooling ber 12 is better able to effect its condensing action upon the gases or vapors ndt only in chamber 12, but also in chamber 9, this also aids very materially and substantially in maintaining a high vacuum conditionin both said chambers 9 and 12, and hence augments the eificiencyof operation of the entire sys dium or mixture of cooling medium and condensates. To lIlSIlIG lSlllS result in one illustrative and practical arrangement, I provide the upper surface of the Shield 16 with raised ledges18, see Fig. 12, so disposed as to form pan or dish portions 67 in said upper surface. These pan or dish portions are disposed over the cups 10, and are provided with openings 17, directly over said cups. With this arrangement the cooling medium and condensates delivered from chamber 12, keep these pan or dish portions. constantly filled and the openings 17 permit the same to pour directly into the cups 10, thereby insuring that the cups 10 are kept constantly filled to enable them to form seals or looks even if, for any-cause, there should be a failure vof a supply ofcooling medium and condensates to said mp5 from the chamber 1.

It is desirable to control the supply of cooling medium to the'vacuumdevices in chamhers 1. I have shown various arrangements for this-purpose. Thus, in Fig. 1, I have shownthe upper and lower portions of pipes 5 providedwith manually-controlled valves 6, 8. It may sometimes be desirable to effect anautomatic control of the supply of the cooling medium and I have'shown various ways of efiecting such automatic control 'bythe height of level of the liquid in chamber 9. In the arrangement 'showna float 32 is arranged to operate in a chamber 68 which is in communication with-the interior of chamber 9 through the connections. 30, 31., whereby the position of the floatis controlled by the height-of level of. the liquid in chamber 9.

, The movements of'this float are utilized to efi'ect the control of the supply of cooling medium. This is' effected, in the arrangement shown, by means of a bar 33- connected to the float 32, said bar eflecting the control of'a valve 7 in pipe 5, through suitable intermediate connections, such as levers 37, 38, 39.

According toanother control arrangement, the supply of cooling medium-from a supply tank 40 into the upper end of the pipe 5 is con trolled by a cone valve 69, which, if desired, maybe protected by a screen 44. 'The' valve 69 cooperates with a cone seat 42 at the bottom of the tank 40 which is in register with the pipe 5. The seating and unseating of this control valve may be effected automatically in any desired or suitable manner. I have shown this accomplished and controlled by variations in the level of the liquid contained in chamber 9, and to this end I utilize the movements of the float 32in auxiliary chamber 68. In that case the bar 33 is'in'the form of a rack bar which meshes withandrotat'es a pinion 34, on a shaft 36, up0n which shaft is carried a drum 35-which operates a flexible cable or other connection 45fconnected to x valve 69.

If desired, and in to still-further treat the gases or vapors which remain after passing through chamber 12, said gases or vapors may be subjected to further condensing,

scrubbing-or absorption action, as conditions may require. For this purpose the gases or vapors pass from chamber 12 through pipe connection 70 into the lower end of a chamber 18 in which, if desired or required, is arranged a perforated supporting late 19 for a mass of scrubbing material, sue as broken particles of coke, stone, brick or the like, the

gases .or vapors being drawn from the-upper end of chamber 18 through connection 20, to which is connected a pump (not shown). Any suitable absorbent material may be employed to the action of which the gases or -vapors passing through chamber 18 are subjected. For example, where hydrocarbon oil vapors are undertreatment I have found that absorbent oil serves the purpose of an absorbent. The absorbent material is introduced into the top of the chamber 18 through a spray device 22, and it collects in the bottom of said chamber, along with any constituent of the gases or vapors which it might absorb, and may be. drained 0E through drain connection 21.

In order to provide against injury to the apparatus or interruption of its operation on account of the development of internal pressure throughaccident or otherwise it is desirable to provide one ormore suitably located safety relief valves to atmosphere. I

have indicated such a safety relief valve at 15 in Fig. 1, as associated with and connected to the upper end of the chamber '12.

It is believed that the operation and mode of procedure in carrying out my invention will be readily understood by persons skilled in the art from the foregoing description taken in connection with the-accompanying drawings.
